Examined in Edexcel 1PH0/2 (Paper 2). Context-based: household appliance energy cost calculations, circuit fault-finding scenarios. Potential difference is a core concept examined in almost every GCSE Physics electricity question. It underpins Ohm's Law, power calculations, and circuit analysis.
What examiners love to ask:
- Calculate energy transferred using E = VQ
- State the voltage across parallel branches
- Explain why a voltmeter is connected in parallel
- Apply voltage rules to series circuits (sum = supply)
- Compare EMF and terminal p.d. (Higher tier)
Typical question patterns:
- "The battery has an EMF of 6 V. Calculate the energy transferred to 4 C of charge." (E = VQ = 6 × 4 = 24 J)
- "Two resistors in series. V₁ = 3 V, supply = 9 V. Find V₂." (V₂ = 9 − 3 = 6 V)
- "Explain how to connect a voltmeter to measure p.d. across a lamp." (In parallel, across the lamp)
